We've discovered the DJI Mini 4 Pro firmware update is still limited. It's pretty disappointing but we still can't use certain accessories not "approved" by DJI. A while back, we received a comment from a loyal viewer who said he was having some problems with his DJI Mini 4 Pro and he believed the firmware update may have impaired his DJI Mini 4 Pro's abilities while on waypoints missions when starting out sideways. Well, today's test puts that into action and you could be surprised by the results. Did it work, or did it flop? ALSO, we wanted to retest an aftermarket battery DJI has recently disabled via one of their DJI Mini 4 Pro firmware updates. If the DJI Fly App displays "Non DJI Battery" in the upper left hand corner of the screen, you're in trouble and the Mini 4 Pro will NOT work properly. Stick around and find out how all this plays out...
